 ### Uppy is pure ESM
 
-Following the footsteps of many packages, we now only ship [ECMAScript Modules](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules) (ESM). Uppy can’t be `require()`’d from CommonJS.

 ## Migrate from Companion 3.x to 4.x
 
-### Minimum required Node.js version is v14.19.0

 Aligning with the Node.js [Long Term Support (LTS) schedule](https://nodejs.org/en/about/releases/) and to use modern syntax features.
 
 ### `companion.app()` returns `{ app, emitter }` instead of `app`
 
-Companion 3.x provides the emitter as `companionEmitter` on `app`. As of 4.x, an object is returned with `app` (express middleware) and `emitter` (event emitter). This provides more flexibility in the future and follows best practices.
